trace_syscalls: Remove duplicate init_enter_##sname()
use only one init_syscall_trace instead of many init_enter_##sname()/init_exit_##sname() Signed-off-by: Lai Jiangshan <laijs@cn.fujitsu.com> Acked-by: Jason Baron <jbaron@redhat.com> Cc: Steven Rostedt <rostedt@goodmis.org> Cc: Frederic Weisbecker <fweisbec@gmail.com> LKML-Reference: <4B14D29B.6090708@cn.fujitsu.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
